Tom Hardy smokes 'Shisha Pen' between takes on the set of new Kray twins biopic Legend... before shooting pivotal scene with screen wife Emily Browning

Acting can be a stressful business, harder still when you’re tasked with the job of playing two prominent characters in the same film – but fortunately for Tom Hardy, he resisted the urge to light up a relaxing cigarette between takes.

The 36-year-old actor plays Ronnie AND Reggie Kray in a forthcoming film, titled Legend, about the notorious London gangsters, charting their rise and subsequent fall during the 1950s and ‘60s.
